TO ALL WHOM IT MAY CONGERN: l

Be it known that I, J. M. TNNER, of Albert Lea, in the'county of Freeborn, and State of Minnesotmhave invented a new. and useful Improvement in Water-Wheel; and do hereby declare that the followingis a full, clear, and exact description thereof, which will enable others skilled in the a'rtto make and use the same, reference being'had to the accompanying drawings, forming part of this specicationQin which- Figure 1 is a horizontal sectional view of my improved water-wheel.

Figure 2 is a vertical' section of the saine, taken through the' line :1: as, iig. l, showing the friction-rollers, and the eccentric path in which they work.

Figure Sis a vertical section of the same, taken through the linc'y y, iig. 1, showing the pivotod guide-armsto which the buckets are'attaehed. Y

Figure llis a vertical sectional view of the same, taken through the line ze, fig. 1, showing the slots in which the' curved buckets work. Y

My invention has f'orits object to furnish an improved water-whe'el,`..simple,in construction, effective in operation, and not liable to get out of order; audit consists in thethin curved buckets attached tothe ends of pivoted arms working in cavities in the heads of the wheel, and operated and guided by wrist-pins,or by frictionwheels or rollers, pivoted to said arms,land workingin eccentric groovesin the casing vof thewh'eel, the whole being constructed and arranged as hereinafter more fully described.

A is the body of the water-wheel, in the face of which are formed any dcsiredinumber of longitudinal slots, for the ingress andegress oi' the buckets B, the number of which will, in each case, depend upon the size oi' the wheel, the amount of'power required, Ste. The buckets B are made thin and curved, and pass into and out of, the body A of the wheel, through the slots in its face. The ends of theibuckets B pass through and work-in curved slots in the end or head-plates C, and their ends are secured to the ends ofthe pivoted arms D. In case the wheel Av be made ofwoththe face of said wheel, at the edges ofthe slots through which the buckets B pass in and out, may be faced with thin iron plates, to prevent their enlargement by the friet-ion and near ofthe said buckets. It' found advisable, a strip of rubber may also be inserted in said slots to serve as packing, to prevent the water from'lowing into the interior of the wheel A. The arms D are pinoted in the recesses formed in the ends or heads of the wheel, or between the two ends or head-plates C and E. The space between the head plates C and E, with'the exception ofthe recesses An which the pi'votcd arms D work,`may belledwith a solid framework, I", or the said recesses may be formed by flanges formed upon one oi' the plates, C or E. To the ends of the arms D are attached wrist or guide-pins, G, which enter and work in eccentric grooves'i'ormed in the casing'H of the wheel, which said grooves Aare so `formed, that, as the guide or `wrist-pins G move along them, thc buckets B will be forced out at the proper time to receive the impulse of the water, and again'withdrawn into the body ofthe wheel A, when said impulse has expended its, force, s o as to be out of the way of the casing H during thcremaining part-dot' the revolution of the wheel. The drawings represent the Wheel as being attached to a horizontal shaft, but this is immaterial, the wheel being so 'constructed'as to operate equally well in any position,.according as the circumstances of each case may render advisable. I are friction-Wheels or rollers, placed upon the guide or wrist-pins G, and which roll along the eccentric grooves, so as to Adiminish the friction in operating the wheel. v I

I claim as new, and desire to secure by Letters Patentl 1. The combination of the centrally-pivoted arnrD, movable buckets B, and body A, all arranged and operating as herein described, for the purpose specified.

2. The thin curved buckets B, attached to the ends of arms'D, pivoted in recesses in the heads of the wheel A, and operated-andv guided by wrist or guide-pins G, or by friction-Wheclsor rollers, I, pivoted'thereto, said pins or rollers working in eccentric grooves in the casing H of the wheel, substantially as Aherein shown and described, and for the purpose set forth.
